Specification of Letters Patent.

Patented Dec. 26, 191G.

Application filed. April 21, 1914. Serial No. 833,404.

To all whom it may concern Be' it known that I, LESLIE E. Moons, acitizen of the United States, residing at Long Beach, in the county ofLos Angeles,

State of California, have invented new and useful Improvements inAutomatic Alarm Apparatus, of which the following is a specification.

This invention relates to an automatic alarm apparatus, and particularlypertains to a mechanism adapted to be mounted on automobiles to preventtheft of the latter.

It is the object of this invention .to provide an alarm apparatus whichcan be read-- ily attached to automobiles and power propelled vehicles,such as motorcycles, motor boats and the like, and which can be set tooperate in event the vehicle is taken by an unauthorized person to soundan alarm and cut oil the motive power of the vehicle.

Another object is to provide an alarm mechanism of the above characterwhich can be adjusted to operate to sound an alarm and stop the vehiclewhen the latter has trav ersed a predetermined distance, and which, whenautomatically operated,wil-l effectively prevent further propulsion ofthe vehicle.

A further object is to provide an alarm attachment for power propelledvehicles adapted to-operatewhen the vehicle has been moved a certaindistance to sound-an alarm and to cut out the propelling mechanism, andin which adjustment can be effected, whereby the alarm will be soundedat any suitable interval before cutting out the motive power.

A further object is to provide a means for setting and adjusting thealarm mechanism and for throwing it in and out of an opera tiveposition, which is controlled by a permutation mechanism to prevent itsoperation by those not familiar with the combination of the permutationdeyice.

In carrying out the present invention 1' provide a chain o't speedreduction gears adapted to be operated by the fiy-wheel of an internalcombustion engine to advance a screw-threaded shaft carrying a revolublemember which rotates when the apparatus is in operation and is adaptedto operate when advanced by the screw-threaded shaft to actuate an alarmmechanism and subse quently cut oil? the flow of gas to the engine, andalso break the electric circuit to the spark plug; the above mechanismbeing incased in a housing and adapted to be shifted to its operative orinoperative position through permutation controlled device.

The invention is illustrated in theaccompanying drawings, in which:

More specifically, 15 indicates a metallic housing or casing which isbox like in form and open on one of its sides to receive a slidingclosure 16 the vertical edges of which are engaged iii-channels 17formed on the inner faces of the side members of the housing 15; thisclosure 16 being designed to be locked in its closed position to preventaccess to the interior of the housing, will be later described.

Mounted within the housing 15 and supported upon one 01" the side wallsthereof is abracket 18, particularly shown in. Fig. 1, the lower end ofwhich is secured to a stud 19 by a screw 20 and the upper end of whichis secured to a stud 21 by a screw This bracket 18 is formed with ahorizontal pen tion extending from the stud 21, a portion which extendsdownwardly at an inclination, its lower end being bent at a greaterangle as indicated by 23 to form an inclined face for guiding themovement of aframe "24 supported thereon. This frame 2- has a lhorizontally extending portion formed with an opening 26 through whichthe bracket 18 extends in slidable contact there with. The lower portionof the frame 24:

is also formed with a horizontally extending member 27 having anelongated, slot 28 therein through which the bracket 18 extends inslidable contact; the member 27 being normally arranged adjacent theupper end of the inclined portion 23 f the bracket, in which position itis sustained by means of a helical. spring 29 wound on the bracket 18and bearing between a pin 30 on the latter andv the underside of theframe member 25. The opening 26 is of such dimensions as to permit arocking movement of the frame 24 in relation to the bracket 18 to thelimits permitted by the slot 28; the frame 24 being normally held withthe inner end of the slot 5 28 abutting against the outer face of thebracket 18 by means of a spring 31 which is secured at one end to thelug 19 and at its opposite end to a depending hanger 32 formed on thehorizontally extending mem- 20 her 2? of the frame 24. The frame 24 isthus spring supported on the bracket 18 and is adapted to be shiftedlongitudinally thereof and rocked in relation thereto, which movementswill be effected, as later de- 25 scribed.

Formed on the member 27 of the frame 2 1 is a bearing in which a. shortshaft 33 is revolubly mounted; this shaft having a friction .wheel 34;mounted on one end thereof,

the periphery of which wheel is adapted to be projected by rocking theframe 24 through an aperture in the side all of the case into frictionalengagement with the periphery of the fly-wheel 36 of an internalcombustion engine. The opposite end of the shaft 33 is provided with apinion 37 which meshes with a toothed wheel 38 formed on a stud shaft 39carried by a suitable bearing on the outer end of the member 27 of the40 frame 24.; the pinion 40 affixed to the toothed wheel 38 meshing witha. toothed wheel. 41 on a stud shaft 12 journaled in the bearing on theupper member 25 of the frame 24.

The toothed wheel -11 carries a beveled pinion 43 on its rear face whichpinion meshes with a corresponding beveled gear 44: having a, flangedhub 15 journalcd in a bearing formed on the frame member 25.

The beveled gear 44 has a threaded central opening 46 therein. adaptedto receive a threaded shaft 47 held against rotation by means of a pin48 thereon engaging a channel 49 on a rigid part of the frame 24 in suchmanner that when the beveled gean 4-1:

is rotated. the threaded shaft 47 will be advanced longitudinallytherethrough.

Formed on the lower end of the shaft C7 is a. collar 50 which isslidably engaged by a sleeve 51 adapted to rotate in relation to thethreaded shaft 47 and to which sleeve is .rigidly' secured a shaft '52arranged in alinement with the shaft 17 and having its lower end guidedin an opening 53 formed in a horizontally extending member 5st on theframe member 32. This shaft 52 is designed to be rotated independent ofthe threaded shaft 47 and irrespective of the longitudinal movementthereof. For this purpose a beveled pinion is mounted on the shaft andconnected thereto by means of a screw 56 whichis threaded in the hub ofthe pinion 55 and extends into a longitudinal channel 57 formed in theshaft 52 in such manner that the shaft 52 may be re- 5 ciprocatedlongitudinally in relation to the pinion and revolved on the rotation ofthe latter. 1

The rotation of the pinion 55 is effected by means of a beveled gear 58mounted on 30 the face of the toothed wheel 38. The lower end. of theshaft 52 is formed with a laterally projecting finger 59 which isadapted when the shaft 52 is lowered as later described, tointermittently strike a plate 60 35 adjustable vertically on ahorizontally rockable sleeve 61 pivoted on a stud 62 and carryingastriker 63 normally held in contact with a gong 6ft. by a spring 65. Theplate 60 is adjusted on the sleeve 61 by means of a thumb-screw 6-5which passes through a vertically extending slot 66 in the plate 60 andengages a flange 67 on the sleeve 61. This adjustment of the plate 60 isprovided for the purpose of disposing it'in different positions inrelation to the lower end of the shaft 52 so that it may be adjusted tobe struck by the finger 59 to actuate the striker 68 to sound the gong64 at various predeterminedpoints in the downward movement of the shaft52.

Interposed in the path of downward travel of the shaft 52 is the arm 68of a bell crank lever mounted on the stem 69 of a normally open cut-offvalve 70; the other arm 71 of the bell crank lever extending upwardlyand connected by a link 72 at its upper end to the lower end of a knifeswitch 73 pivoted at 7 1 on the side wall of the case The valve 70 isdisposed within the case 15 and connects at one side with a pipe 75leading from a source of gas or hydrocarbon supply, as a'tank 76, andconnects on its opposite side with a pipe 77 leading to the carburetor78 of the engine 79 for driving the vehicle indicated at 80.

The arm 68 of the bell crank lever has its outer end adjustable by meansof a set-screw 81 by which the point of its engagement by the shaft 52may be varied as occasion requires; this bell crank lever being designedto be operated by the downward movement of the shaft 52 to close thevalve 70 and thereby cut ofl the flow of fuel to the carburetor 78 andengine 79 and simultaneously move the knife-switch 73 out of engagementwith a contact 82, and thereby break an electric circuit throughconductors 83 leading from one/side of the magneto coil 84 of thecontact 82, and a conductor 85 lead- 30 of reciprocal :1 be reciprocated'lUllglttl the horizontal portion of the bracket 18 with.

its peripheral edge normally bearing against a friction roller 89mounted on the upper edge of the frame member 2 1, as part1cnlarly shownin Fig. a. This cam disk 88is normally locked against movement and isunlocked and operated by a permutation device to prevent unauthorizedpersons from manipulating the same to throw the alarm mechanism in orout or operation.

The cam disk locking means isparticularly shown in Fig. 3, and comprisesa series o s, here shown as in number, and des These rods exterupper-end of ends projecting finger engaging iorizontally adjacent thecase 15 with their outer through and titted with by which they mayoinally in an outward direction in opposition to s rings 95 bearingbetween pins 96 on the rods, and a dependent hanger 97 carried. by thetop plate of the case 15. The inner ends of any one or more of the rodsnormally project into sockets formed in the face of the cam disk 88; inthis case the rods 00 and 91being shown as normally engaging sockets 98and 99, thus holding the cam disk against movement.

The inner ends of the rods 92 and 93 are connected to levers 100 asshown in Fig. 1, whichin turn are connected to short bars 101 and 102normally positioned out of contact with sockets 103 and 104C in. the camdisk 88. The cam disk and the locking rods are concealed within the caseso that it is necessary for the operator to know which one of the rods90, 91, 92 and 93, singly or collectively, must be pulled in order torelease the cam disk. In this illustration the rods 90 and 91 comprisethe locking rods and the rods 92 and 93 are the guards; these guard rodsoperating when pulled, to advance the bars 101 and 102 into the sockets103 and 104 in the cam disk so as to lock the latter against movement,from which it will be seen that if the rods 90, 91 and 92 are pulleddownwardly. while the cam disk is released by the withdrawal of the rods90 and 91, it will be locked by the introduction of the rod 101 to thesocket 103.

It is manifest that the number and arrangement of these rods may becarried out ated 8.390, 91, 92 and 10%. This hand hold is provided witha shank 105 adapted to extend through a slot 106 in the top of the case15 and also through an aperture 107 in' a peripheral flange 108 formedon the cam disk 88 with the lower end of 'the shank 105 terminatingadjacent the face of the portion of the bracket 18 in which the cam diskis pivoted.

The lower end of the stern 105 is formed with a cutaway portion 109,which, when the hand hold 104; and stem 105 thereon are turned to apredetermined position, will perrnit the stem to pass an abutment 110mounted on the bracket 18 adjacent the cam disk 88, as illustrated inFig;- 5, and which abutment operates to engage the stem 105 to preventrocking of the disk 88 when the stem 105 is not turned to its proper.position.

To determine the necessary position of the stem 105 in order that thecut-away portion 109 will clear the abutment 110, a dial 111 is formedon the hand hold 10% and formed with numbered radial lines, one of whichextends directly at right angles to the wall of the cut-away portion109. In the illustration of this device in Fig. 6, this line is numbered6, and when this line is positioned to extend in alinement with an arrowor other mark 112 formed at the outer edge of the slot 106, the cut-awayportion will be positioned as shown in Fig. 5 so that the stem 105 willpass the abutment 110. The hand hold 104: is held against displacementby means of a cotter-pin 118 which is passed through the stem 105adjacent the underside of the flange 108, as shown in Fig. 4.

1n the application of the invention the case 15 is rigidly attached tothe frame of the vehicle in such manner as to prevent its being easilyremoved and is arranged with the opening 35 adj agent the periphery ofthe fly-wheel '36; flanges 114 on the case 15 on the marginal edges ofthe slot 35 projecting in close proximity to the periphery of thefly-wheel to prevent the introduction of implements for the purpose ofinterfering with the operation of the device.

Ordinarily the parts are disposed as shown in full lines in F ig. 1,that is, with the frame 24 in its uppermost position and friction disk34 out of contact with the fly wheel 36. The threaded shaft 47 will alsobe in its uppermostposition and the bell crank lever on the valve stem69 will be disposed in its uppermost position by the action of a spring115. When the parts are thus disposed the circuit from the magneto coil84: to the spark plugs 90 is closed and the valve 70 is open to permitthe passage of the hydrocarbon mixture from the tank to the carburetor78.

The engine 7 9 can be set in operation without aii'ecting the alarmdevice.

When it is desired to set the alarm device to prevent theft of thevehicle the operator manipulates the'hand hold 104 and the cam disklocking bars according to their combination so as to release the camdisk and position the hand hold so that it may be moved to rotate thecam disk and thereby cause'the latter to bear downward on the upperportion of the frame 24 to shift the latter in opposition to the spring29. The downward movement of the frame 24 causes the end of the slot 28to ride over the underside portion its enlarged portion against theframe 24, in

which position it is locked by the engagement of one of the locking barswith asocket 116 with sockets 1.17 and 11S positioned opposite thelocking bars 101 and 102. When thus positioned the hand hold 104 will beturned so as to move the cut-away portion 106 out of alinement with theabutment 110 so that in event the locking bars are successfullydisengaged from the cam disk the latter cannot be readily operated.However, the apparatusis designed to be concealed within the vehicle asmuch as possible and the gripping rings 94 of the locking barsare hiddenbeneath an overhanging shelf 119 so as not to be apparent to theordinary observer.

The operation of the invention will now be as follows: Assuming that theengine 79 is set in operation by an unauthorized person with the-intentof wrongfully using or operating the vehicle and that the device isadjusted as just described. The rotation of the fly-wheel 36 will act torevolve the friction wheel 34 which in turn will operate through thepinion 37, toothed wheel 38, pinion 40, toothed wheel. 41 and pinion 43to rotate the beveled gear 44 and the pinion 55, this latter beingrotated by the revolving of the beveled gear 58 on the toothed wheel 38.The rotation of the beveled gear 44 will operate to advance the threadedshaft 47 in a downward direction, thus advancing the v shaft 52, whichwill be rotated by the action of the pinion 55. The downward movement ofthe threaded shaft 47 is designed to be slow so as to permit the persondriving the vehicle to travel a predetermined distance before the lowerend of the shaft 52 will be advanced sufliciently far for the finger 59to strike the plate 60. The unauthorized driver of the vehiele can thustravel a distance Without being made aware of the presence of the alarmmechanism, which has been previously set by adjusting the plate 60 tooperate at a predetermined distance of travel of the vehicle, whichpoint is governed by the distance of the plate 60 from the lower endofthe shaft 52. By this arrangement the alarm will be sounded when thevehicle is in motion and while occupied by the unauthorized person,thereby reasonably assuring the ascertainment and capture of suchperson, which ordinarily would not be possible were the alarm set offaatthe time of starting the engine. When the shaft 52 has been advanceddownward a sufficient distance the finger 59 will strike the plate 60,thereby rocking the sleeve 61 in opposition to the spring 65 and causingthe tapp er 63 to rapidly strike the gong 64 to sound the alarm.Immediately thereafter the shaft 52 will move into engagement with thearm 68 of open the slide closure 16, which is normally locked by meansof one of a pair of reciprocal bolts 127 and 128 mounted in a guide 120on the floor of the case 15; the bolts 127 and 128 being connected tothe opposite ends of a short lever 121 pivoted at 122 and positioned bymeans of a spring 123 on the bolt 127 in such manner that one of thebolts will be normally disposed in an advanced position and the other ina retracted position. Connecting with the lever 121 is a cord 124, whichpasses around a direction roller 125 and is connected at its upper endto the lower member 27 of the frame 24 in such manner that when theframe 24 is in its lowermost position to relax the cord 124 the spring123 will maintain thebolt 127 in its advanced position in engagementwith a lug 126 on the underside of the closure 16 and when the frame 24is in its uppermost position the bolt 127 will be retracted inopposition to the spring 128 and out of engagement with the lug 126 andthe bolt 128 will be advanced into engagement with the lug 126 by reasonof the lever 121. It'thus becomes necessary to dispose the frame 24 inanin:

tel-mediate position in order to arrange the bolts 127 and 128 both outof connection with the lug 126. This can only be effected the bolts 127and 128 in relation to each ner s other. different positions of the camdisk Will accordingly be necessary to position the bolts 127 and 128clear of the lug 126. if desired, the lever 68 can be adjusted by meansof the set screw 81 to operate in advance of thelever so as to stop thevehicle without sounding an alarm, or it may be adjusted, to operate atany desired time in relation to the sounding of the alarm.

By the use of this invention the proprietor of a power propelled vehiclecan leave the vehicle unguarded with the assurance that in event it ismaliciously taken that an alarm Will be sounded and the vehicleautomatically stopped Within certain limits and by reason of thecombination locking mech anism controlling the alarm mechanism theproprietor of the vehicle will have a secret combination lock for guarcling the vehicle against. theft or improper usage.
